Suppose we have an application running on a 8-processor distributed-memory multiprocessor, which has a 100 ns time to handle reference to a remote memory. For this application, assume that all the references except those involving communication hit in the local memory hierarchy. Processors are stalled on a remote request, and the processor clock rate is 4 GHz. If the base CPI (assuming that all references hit in the cache) is 0.5, how much faster is the multiprocessor if there is no communication versus if 5% of the instructions involve a remote communication reference?
